They've become the dessert everyone asks for when summer rolls around.

Playful Kitchen Ideas
I often swap in different berries for new looks and tastes. A bit more coconut or some lime zest brings fresh dimensions. Adding rum-soaked cake makes grown-up versions perfect for backyard parties showing how flexible this basic idea can be.
Saving Sweet Moments
They're tastiest day-of when the frosting still looks perfect. Store any leftovers in a covered container in your fridge let them warm up before eating. When I take them to gatherings I bring the frosting separately and decorate on-site so they look their absolute best.

Frequently Asked Questions
- → How far in advance can I bake these?
The cupcakes and filling can be prepped 2 days early. Assemble and frost on the serving day for the best taste.
- → Why remove pineapple juice?
The juice adds flavor and moisture to the batter, but draining it stops the filling from turning soggy.
- → Is it okay to use actual rum instead?
You can swap the rum extract for 1 tablespoon of dark rum. The taste will be subtler but still delicious.
- → Why chop up the coconut flakes?
Smaller pieces are easier to work with when sprinkling or eating. Big flakes can make things messy!
- → Can frozen berries replace fresh ones?
Fresh berries give brighter color and flavor for the frosting. If using frozen, make sure they’re thawed and drained well.
